Abstract
1,249,702. Change-speed control; friction clutches. CATERPILLAR TRACTOR CO. 15 Jan., 1969 [25 Jan., 1968], No. 46173/70. Divided out of 1,249,701. Headings F2C, F2D and F2L. The subject-matter is the same as that of the main Specification 1,249,701, but the claims are directed to the single-disc clutch (28), see Fig. 6A in the abridgment of the main specification, which, during the concluding stages of a gear shift sequence, applies accelerating torque to the gear input shaft (22) before the main clutch (21) begins to re-engage, this clutch (28) having previously been in slipping engagement whilst the synchronising brake (36) was applied.
